Andreas Kling 9c6999ecf2 LibWeb: Implement "NodeIterator pre-removing steps" ...

These steps run when a node is about to be removed from its parent,
and adjust the position of any live NodeIterators so that they don't
point at a now-removed node.

Note that while this commit implements what's in the DOM specification,
the specification doesn't fully match what other browsers do.
